/*! \file async_shell_cmd.hpp
   \brief We still use some unix commands for convenience, and we did not have to replace them by system calls
   \ Instead of calling C system(...) that can take a lot of time (creation of a process, etc), in many cases
   \ it doesn't hurt to do this asynchronously, may be we must tweak thread priority, pin it to a CPU, etc (TODO later)
